Growing Kale in Hydroponic Farming: A Comprehensive Guide

Kale, a superfood known for its adaptability, flavor, and nutritional value, is becoming a favorite in hydroponic farms. This comprehensive guide explores the fascinating journey of growing kale in hydroponics, covering various aspects from seed selection to innovative pathogen prevention using the AirROS system.

Starting with the Seeds

Growing kale begins with selecting the right seeds. Curly kale or Scots kale are popular choices known for fast growth. Seeds are often placed in growing cubes for germination, taking 5 to 8 days with proper care. For commercial growing, a Vacuum seeder can be used to speed up the process, and pelleted seeds wrapped in clay make handling easier.

Types of Hydroponic Systems for Growing Kale

  • Deep Water Culture (DWC) System: Excellent for kale’s larger roots. Commercial growers use floating Rafts, while hobbyists may prefer the Bucket DWC System.
  • Kratky Method: Simple and time-saving, with partial exposure of roots to air.
  • Water Depth Consideration: In DWC, the water should be at least 12 inches deep, providing ample space for root growth.

Optimum Growing Environment for Kale

The environment plays a crucial role in kale growth. The temperature has to be maintained between 16 °C to 24 °C. Electrical Conductivity (EC) should range from 1.6 to 2.5, and pH should be between 5.5 to 6.5. Kale grows well under artificial lighting, especially far-red light. Sometimes a combination of green and far-red light is used to increase yield.

Management of Nutrients

Nutrient management is vital for healthy kale growth. For instance, all leafy greens, kale consumes high amounts of nitrogen for bigger leaves and more phosphorus during the root development phase. Frequent monitoring of EC helps in adjusting levels for optimal nutrient uptake. It’s essential to measure the temperature of the nutrient solution, as high temperatures reduce the oxygen-holding capacity. Kale is ready to harvest after 4 to 5 weeks of transplanting, offering fresh and nutritious leaves.

Pathogen Prevention In Kale hydroponic Farming

    • Regular Monitoring and Sanitation: Inspect plants for signs of disease and pests and cleaning equipment to maintain a healthy environment.
    • Biological Controls: Introduction of beneficial insects to control pests naturally.
    • Use of AirROS System: Integration of the AirROS system for innovative pathogen prevention.
    • Environmental Controls: Maintaining optimal temperature, humidity, and airflow to prevent the growth of pathogens.
    • Nutrient Solution Management: Regular monitoring and adjustment of pH and EC levels to prevent nutrient-related issues that can lead to disease.
    • Quarantine Procedures: Isolating new or infected plants to prevent the spread of diseases within the hydroponic system.
